Forging roll is a plastic working technology that combines the principles of rolling and forging. It involves placing heated material between rotating rolls and continuously plastically deforming it to form a desired cross-sectional shape and length. This processing method is characterized by its ability to refine the material's fiber structure, thereby improving its strength and toughness. Typical processing methods include cross rolling, taper rolling, and profile rolling, which are particularly effective for manufacturing long shafts and parts with complex cross-sections. It contributes to improving material yield and reducing subsequent processes in fields such as automotive parts (crankshafts, camshafts, axle shafts, etc.), construction machinery parts, railway vehicle parts, and tools.
